RADIATOR-DRUM.

SPECIFICATION forming part` of Letters Patent N o. 533,887, dated May '7, 1895.

` Appntaitnhed December 22,1894.. sean No. 532,679. (No man.)

To all whom it may concern.- p

Be it known that I, TILGHMAN B. SNYDER, of Snyders, in the county of Schuylkill and State of Pennsylvania, have invented certain new and useful Improvements inRadiator- Drums; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form part of this specification. s

This invention is an improved smoke-drum or hot air radiator and its object is to enable the smoke or hot air to be caused to circulate through the radiator in various ways so as to obtain the greatest amount of heat therefrom and retard or expedite the passage ot' the hot air therethrough as may be desired.

It consists therefore in the novel construction and combination of parts hereinafter described and claimed.

Referring to the drawings, Figure 1 is a per-l spective view of the upper and lower drums and intermediate pipesection of the radiator, the latter being separated from the drums, so as to expose the interior construction of the latter. Fig. 2 is a longitudinal vertical section through the bottom drum, showing the main damper in two positions by aid of dotted lines. Fig. 3 is a side View of the top drum with side wall broken away to show the 4interior thereof.

As represented in the drawings, my radiator comprises an upper drum or head, a lower drum and a series of'intermediate pipes connecting said drums.

'Ihe shape of the drums is not essential; and may be varied, and the external ornamentation may be as ornate as desired.

The lower drum (A) is hollow and has a central smoke inlet opening (a) in its bottom, its

,the drum.

distant openings (eight being shown) in it, and the bottom (E) ot' thetop drum has a series ofsimilar openings in it, the ends of a series of pipes (P, Q, R, S, T, U, V, WV) being connected to the upper and lower drums at such openings.

The upper drum (E) has a central transverse inclined partition (F), on one side of which is a partition G and on the other side thereof a partition H which altogether divide its interior into four chambers l', 2, 3, f1', as shown.

In the lowerdrum (when damper B is closed as shown in Fig. 1) pipes P, Q, R, communicate with chamber l; pipes U, V, with chamber 2; pipes S with chamber 3; and pipes W, T, with chamber 4.

In the upper drum, pipe Q communicates withchamber 1'; pipes P, U, communicate withr chamber 2'; pipes R, S, T, with chamber 3 and pipes V, W, with chamber 4.

The partitionsin the drums are so arranged with reference to the pipe openings that the above described communications between .pipes and chambers are always maintained in to communicate with chambers 4 and 3, and

shut ott from chambers 2 and l. y

In partition D (of drum A) is an opening d which can be closed by a damper d operated by a rod (d2) extending through the side of When said damper is open there is a direct communication between chambers 3 and 4. When damper B is closed the smoke inlet (a) communicates only with chamber 3. When said damper is closed said inlet communicates with both chambers 1 and 2, but not with chamber 3. The end of partition C is beveled so as to tit neatly against the damper when thelatter is closed, but when the damper is opened the point ofpartition C projects into chamber 3, while communication is established under the damper B between chambers 1 and 2. Damper B is slotted (at b) to allow it to rock past the end of partition C.

In partition Gof drum E is an opening (g) provided with a damper (g) operated by a rod (g2) extending through the side of the drum,

and when said damper is open there is a direct communication between chambers l and 2.

The outlet openingl e in the top of drum E communicates with chamber 1 only, in the construction shown.

A damper r is placed over the top of pipe R in chamber 3 of drum E, said damperhav ing a shank (r) which projects through an Opening in partition F into chamber l and its end underlies an inclined rib g3 on the back of damper g. Shank r is pivoted at r2 and when damperg is opened the rib gpresses down the end of the shank and lifts damper r so that both dampers g and r will be opened and closed simultaneously. If desired damper o may be independently operated.

The construction will be clear from the foregoing description and drawings, and will work out correctly, though owing to the numerous chambers it may appear confusing.

The operation is as follows:

For dt'1-ectcZrccft.-Open all dam pers. Smoke enters both chambers l and 2 of lower drum, rises direct through pipes P, Q, U, into chambers l', 2', ot the upper drum, passes from chamber 2' into land out through opening e.

For threeway smoke passage-Shut damper B, and open the others. Smoke enters chamber 3 and chamber 4 (through 3) of lower drum; rises through pipes S, T, NV, into chambers 3 and 4 of upper drum; descends through pipes V, R, into chambers l, and 2, of lower drum; rises through pipes l), Q, U, into chambers 1,2, of upper drum, and escapes through opening e.

For tortuous multiple passage-Close all dampers. Smoke then enters chamber 3, rises through pipe S into chamber 3'; descends through pipe Tinto chamberi; rises through pipe XV into chamber 4'; descends through pipe V into chamber 2; rises through pipe U into chamber U; descends through pipe P into chamber l; rises through pipe Q into chamber l', and escapes. In this case the smokegoes up four times and down three times; pipe R being cutout ofthe circuit- Obviously the number of pipes may be increased, and various changes made in the mechanical construction without departing from the essential invention, which is summarized in the claims.

Having thusdescribed my invention, what claim as new, and desire to secure by Letters Patent thereon, is-

1. The combination ot the lower drum having a central transverse damper, and two chambers on each side of said damper; and the upper drum having an outlet opening, two non-communicating chambers on one side of said opening, and two communicating chambers on the other side of said opening, and a damper for closing the communication between said opening; with the series of pipes connecting the said drums, for the purpose and substantially as described.

2. The combination ofthe lower drum having a central transverse damper over the inlet opening, two chambers at each side of said damper, and a damper adapted to establish communication between two chambers at one side of the main damper; said main damper being adapted to make communication between the other two chambers when it is opened; with an upper chambered drum and connecting pipes, substantially as described.

The combination of the upper drum having a central transverse partition, two noncommunicating chambers at one side of said partition, and two communicating chambers at the other side thereof, one of which coinmnnicates with the escape flue; and a damper for closing communication between the two latter chambers; with a chambered and dampered lower drum,and pipe connections, substantially as described.

et. The combination ofthe lower drum having four'chambers, one of which communicates with the inlet flue or pipe; with the upper drum having four chambers, one of which communicates with the escape flue or pipe; with a series of pipes connecting said drums, the pipes being so arranged that the smoke will be caused to alternately ascend and dcscend successively through the pipes and pass successively through all the chambers, substantially as described.

In testimony that I claim the foregoing as my own I aiix my signature in presence of two witnesses.
